How's this for potty training?! :)

I was getting B ready for his bath last night, I took his diaper off and set him down beside me while I took care of the diaper. So he is standing there beside me and all of a sudden my foot (I had on sneakers) feels warm. I look down and he is looking up at me grinning, while peeing on my shoe. I picked him up and put him in front of the toilet and told him we potty in the toilet, not on mommy. He squeals, does a little dance and runs off to his room. He is such a goof.
